“This being our first burglar alarm we found the survey and initial advice from SDS very helpful in making our decision. The engineer was very efficient and nothing was a problem, all in all a great company and have recommended to friends who have all had a positive experience”.

“We have found the office and managerial staff, surveyors and engineers all to be extremely efficient. The results of their efforts and services are always helpful and conclusive. This means that we will always use and recommend them, without question. We wish that all services were as outstanding as SDS.”

Jenny. North London

“We started using SDS back in the 1980s, in south-west London, and have called on them ever since for our premises’ security needs, most recently when we moved to our new SE1 offices in September.
The alarm systems have been reliable and problem free.
Justina and the other office staff are both helpful and efficient, and the engineers friendly and skilled. SDS has again helped us to achieve a low-stress relocation.
We are a company of corporate copywriters. We aim to build long-term relationships with our clients through providing a high standard of service. We appreciate it when suppliers – such as SDS – work in the same way.”

Sally LangDirector, Lang Communications London SE1

“We have been SDS customers for our intruder / fire alarm for more years than I can remember – at least 20, I am sure. We initially chose SDS because they were local and highly recommended. We have regular annual maintenance and the system has always been very reliable, with as far as I can remember only ever one non-scheduled call out. The best thing of all is that for the rest of the time we simply don’t need to think about it. I can’t imagine us ever going elsewhere.”
